Resumen
The growing number of modern grocery stores in Indonesia is a challenge for each grocery store to maintain and increase their number of consumers. The success of maintaining and improving service quality will affect long-term profitability and business sustainability. Therefore, in this study, we examined consumer perceptions of service quality in one of modern grocery stores in Indonesia. Data were collected from 387 consumers of grocery stores in Jakarta, Bogor, Depok, Bekasi, Cibubur, and Subang. Structural Equation Modeling (SEM) through Maximum likelihood and Bayesian estimation was employed to analyze the data. The finding indicated that the five indicators of the retail service quality scale consisting of physical aspects, reliability, personal interactions, problem solving and policies provided valid multi-item instruments in measuring consumer perceptions of service quality in grocery stores.
